How many tearful separations, sweeping romantic gestures, and grand reunions has the Big Apple hosted on screen? I've seen a lot of New York-set romances, but I've never seen this location (or even heard of it), so when I interviewed Gluck, I had to ask him about enshrining it in the NYC rom-com canon. "The Lighthouse means a lot to me, which is why I wrote that," Gluck explained. That book, 'Little Red Lighthouse,' is a real book that my parents read to me [...] No one on the crew knew it existed. I love going to locations that have never been shot before [...] New York — living, breathing New York — is so much more than the tourist attractions."
